"Stop!" At the moment when he was close to the critical distance! Lieutenant Colonel Grant, who was sweating profusely, issued an order! After ascending, he could still pray that the Chinese Navy would let him go! But if it hit, I am afraid that it would be much stricter! At the last moment, he finally lost the courage of the Chinese Navy! Reluctantly, he issued an order, "Let's float!"

Being forced out of the water is the greatest shame for a diver! But after hearing Grant's order, from Executive Officer Billy Hellington to George Carlson, who had just joined the submarine, no one showed shame, and Fan let out a long breath! I was glad that Grant had made a final decision!

If they lived, no one wanted to die! The consequences of the impact were something they couldn't bear anyway!"Lieutenant Colonel, shall we continue to leave after we surface?" the soldiers who survived the catastrophe asked about their next steps.

"No, stop when you float to the surface and open the door! I want to see what kind of ghost the ghost is!" This ascent has already made Grant lose face, and he may be punished by his superiors when he returns! But if he can obtain information about the opponent's new submarine, then maybe he can also be rewarded by his superiors!

"Yes, Lieutenant Colonel!" the submarine slowly floated up, and in a short time it was above the water, and Lieutenant Colonel Grant couldn't wait to open the door of the boat, and greedily breathed a breath of fresh air that he had not seen for a long time, and he was intoxicated by the salty smell of the sea breeze!

"Judging from where they were, if they were to float up, they probably might be in that position!" Billy Hellington, holding the telescope, pointed ahead.

"If it's a new type of submarine, I don't think the Chinese Navy will" Before he could say anything, Billy Helrington closed his mouth and pressed his eyes to the telescope, "I see the periscope! The one in front of me is about to go to the surface!"

"The rear too!"

"And the right front!" the two soldiers and his colleagues almost spotted the submarine that was about to surface.

"Give me the camera!" Grant snatched the camera from George's hand and pointed the camera at the nearest submarine directly in front of him, "Come on, baby, let me see what you look like!"

"Oh my God! how is it possible?" As soon as the shutter was pressed twice, Grant stopped the operation, and looked at the extremely familiar submarine not far away with an incredulous face, "Isn't this model a Song-class conventional submarine of Huaguo?"

"The other two, too!" In the moments leading by, Billy Hellington had already swept around with his telescope in his hands to take in the three almost identical submarines!

"How did they catch up with us?" I have memorized the number of Song-class conventional submarines! It may have some performance from the performance just now!" Grant took the telescope from Billy's hand and pressed the eyepiece almost into his eye socket.

"When I was only a nautical mile away from the other party, I found that the shape of this submarine was very similar to that of the Song-class! But the noise model was completely different from the Song-class!" the sonar soldier who had been suffering just now also interjected, "And if it was the Song-class, I would have discovered them a long time ago!"

"Could it be the new model of the Song-class series?" Grant asked suspiciously, but in an instant he reversed his guess, "but looking at the hulls of these submarines, they have obviously been in service for a while!"

"This is China's territorial waters, please leave immediately!" At this time, a huge horn sounded from the submarine directly ahead, and the Chinese soldiers on the bridge shouted loudly in standard rice-style English.

"Let's go! we're going to get in trouble if we don't go!" Billy Helrington was the first to climb down! Then the sonar soldier and George and the others! Grant stayed last, and he reluctantly glanced at the three submarines before slowly climbing down. Then the Los Angeles-class nuclear submarine slowly sailed out of China's territorial waters under the surveillance of three conventional submarines!

A few days later, all the officers and men of the three submarines at a certain naval base in Huaguo received a warm welcome from the base: "You have given our navy a big face this time! I have already reported your merits to my superiors, and you will receive commendations for how long it takes to make up for it!"

"Thank you, chief! But I don't dare to take credit, this is all the effect of the submarine after refit, even if it is replaced by someone else!" replied Major Li Changgan, the leader of the submarine detachment.

"This time, the weight of the battery has been reduced by one-third, but the reserve of electric energy has more than tripled! Moreover, the noise of the propeller and the main engine reduction gearbox processed by the new technology has been greatly reduced! The speed of underwater navigation has been greatly increased! If we can't catch up with a mere Los Angeles-class, then we don't have to mess around in the navy!" Li Changgan gave all the credit to the renovation project.

At present, conventional submarine batteries are still dominated by lead-acid batteries. The specific energy of lead-acid batteries is about 35-45wh/kg, and the general conventional submarine needs 1-2 hours of full-speed diving ability, or 3-7 days of low-speed diving ability. According to the estimation of a conventional submarine with an underwater displacement of 1500 tons, the battery usually costs about 50-100 tons.

With the new battery technology, the weight of the battery has been reduced to 60 tons, but the energy contained in it can give them 4-8 hours of full-speed capability and 3 weeks of low-speed latent capability! This is enough to extend its monitoring range to the position reached by Lieutenant Colonel Grant's Los Angeles class.

The biggest source of noise for submarines is the propeller and the main engine reduction gearbox, and the adjustment of these two parts reduces the noise intensity of their driving, so until the Los Angeles class is surrounded, their sonar crews did not notice!

"Haha! Things are good things! But there are also people who can use them!" The commander of the base patted Li Changgan on the shoulder affectionately, "Write a detailed copy of the process of forcing the Los Angeles-class nuclear submarine to the surface this time! This will be an important basis for us to study the new submarine improvement work and the Los Angeles-class!"

"Yes! Guarantee to complete the task!" Li Changgan immediately stood up and saluted.

"Lieutenant Colonel Grant, are you sure you're hallucinating because you're taking too many drugs?"

"That's absolutely right! I still have photos taken at that time, judging by the style of the shells, they are definitely Song-class conventional submarines!" Grant took out his camera and placed it in front of these people!

"Oh my God, how is this possible?" the senior officials of the Mi military naval base also fell silent. (~^~)
